Romans 8:10

And if Christ is in you, the body is dead because of sin; but the spirit is life because of righteousness. [That the fleshly mind leads to death is obvious, for the mind of the flesh is opposed to the God of life, since it is not only not subject to him, but can not become subject to him: so they that cherish it can not please him. The mind of man must be changed from carnal to spiritual, and he must cease to serve the flesh before he can serve God. But ye Roman Christians are not carnally, but spiritually minded, if indeed ye are truly regenerate, so that the Spirit of God dwells in you. If ye have not the Holy Spirit who proceeds from Christ, ye are not regenerate, ye are not his. And though Christ dwells in you (representatively by means of his Spirit), your body is doomed to natural death (and hence is to be accounted as already dead) because of (Adam's) sin; yet your spirit lives because it is justified and accounted righteous (by reason of Christ).]
